Your oldest gear?

My oldest piece is a Citation I preamp likely from the early sixties.  After fixing it up I was curious about the pre-RIAA record playback curves.  It’s become a gateway into the world of 78s and early LPs.

Longest owned still in use is an AR-XB I bought used in the late 70’s.  I replaced the tone arm with a more flexible Jelco and it sounds decent with the above mentioned Citation preamp.

One of the Eico sets is modified with fixed bias, chokes and triode input. The other just recapped. The Lambda is a tube regulated bench supply that I use with the preamp. 401s are all AudioGrail refurbished.

Sansui 8080

Concept 2QD

ADS L810

1965 McIntsosh Mc240

1965 McIntosh Mx110z

1965 McIntosh MR67

Purchased 2/3 in 1978 (still have original receipts from both 1965 and 1978) - Mx110z replaced the 1965 C24 last year.  Mc240/Mx110z have had PSUs rebuilt and cap work.  They sound great to my ears.
